lNoloAToR FOR BALING-PVREs-SES.

SPECIFICATION forming part of Letters Patent No. 728,51 5, dated May 19,1903.

Application filed February 27, 1908. Serial No. 145,362. '(No model.)

' for Ealing-Presses, of which-the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

Our invention relates to an indicator for service in affording signalsupon the com#V pletion of bales formed in baling-presses, whereby theoperatoris notified that sufficient material has been fed into the pressto constitute the bale of a size desired.

The invention consists in features of novelty hereinafter 4fullydescribed, and pointed out in the claims.

Figure I is a front elevation of our indicator. Fig. II is a rearelevation. Fig. III is a vertical section taken on line III III, Fig. I.Fig. IV is a cross-section taken on line IV IV, Fig. I. Fig. V is across-section taken on line V V, Fig. II.

A designates the top wall ofa baling-press box containing a longitudinalslot B, located in the path of travel of the material formed into a balein said box. j

1 designates a standard mounted on the wall A adjacent to the slot B.This standard is provided with auA elongated aperture 2.;

(See Figs. II and III.) 3 is an upright slidably held to the standard 1by a nut 4 and washer 5,applied to an elongated' boss 6, that fitswithin the elongated aperture 2 in said:

standard. The upright is also held to the standard by flanges 7,projecting from its edges at the lower end and embracing the standard. v

8 is a stub-shaft carried. bythe upright v3 at its forward side.

9 designates a disk journaled on the stubshaft 8 and provided at itsforward sidewith a series of elongated lugs 10.

11 designates bolts vinserted through the disk 9 and lugs 10 and bearingnuts 12.

13 designates adjustable plates provided with slots 14, which receivethe lugs 10. These plates 13 are preferably of segmental shape, and theyare held to the disk 9 by the bolts 11, which pass therethrough tosecure them in radially-arranged positions.. Each plate 3 by a bolt 18,that passes through an aperture 19 in'said upright and ybears 4a nut 20,by which the bolt is heldin a fixed position in said slot at any desiredelevation to support the plate 1-7.

21' is a gong supported by the plate 17. 22 is a trip-hammer pivotedat-23to the plate 17 and having an arm 24, that projects from itspivotal point into the path of travel of the pins 16 on'y the plate 13,that carries them. v j

25 is a retractile spring having one end con nected -to the plate 17Aand the opposite end connected tothe trip-hammer 22. In thepracticalruse of our indicator the adjustable serrated plates 13 are adjusted. inwardly or outwardly to diminish or increase the'circumferenceof the series of plates'in wheel form, so that such 'circumference willcorrespond to the length of the bale which it .is desired to form in thebaling-press box. It

willbe seen that in this connection a very considerable circumferentialrange is projust the trip-hammer 22, so that its arm will projectproperly into the path of travel of the pins 16,- to be struck therebyand cause the trip'- hammer to be moved and rebound to ring the gong 2l.In the ac t of baling the In the readj ust- .ment of the plates 13 it isnecessary to readmaterial in the baling-press boxthematerial eengages'the serrationsl of the plates 13 as it passes beneath them,thereby causing the plates to travel in a circular path. When the disk 9has been carried near a complete revolution in the movement of theplates 13, the pin 16 that first encounters the trip-harnmer arm 24trips said hammer and causes an alarm to be sounded to indicate that thebale lroo is almost completed. Vhen the next pin 16 strikes said arm, analarm is sounded to indicate that the baleis complete. As the bale ofmaterial is formed in the press-box of the baling-press to which ourindicator is applied the Wheel of the indicator, composed of the disk 9an d the plates 13, gravitates in the slot B of the press-box, restingconstantly on the bale, and is rotated by the material of the bale asthe forming;r of such bale progresses. This gravitation of theindicator-Wheel is permitted by the slidable connection bet-Ween theupright 3 and the standard 4 of the indicator, the boss 6 moving freelydownwardlyin the slot of said standard and being retained in the slot 2of the standard during such movement by the nut 4, which is preferablybacked by the washer 5. The advantageof this arrangement is that thematerial of the bale be ing produced provides an actuator for theindicator-wheel,and said Wheel readily and continually adapts itself tothe surface of such material whether even or uneven. In the event ofunevenness of the bale material at the top side, Where it contacts withthe indicater-wheel, the wheel accommodates itself to such unevenness,and no rotation thereof is lost, the Wheel gravitating and turning asfreely on an uneven surface as upon an even surface. It Will also beseen that the Wheel willaccommodate itself to the o'li'sets bet-Ween thebales produced by the division-blocks located between them, which arelower than the bales, and will therefore be constantlyin the properposition to be engaged by the next succeeding bale.

We claim as our invention-- In an indicator for baling-presses, thecombination of a slotted standard, an upright movably secured to saidstandard, a disk rotatably supported by said upright, a series ofsections extensibly carried by said disk, a plate adjustably secured tosaid upright, a gong mounted on said plate, and means for sounding saidgong on the rotation of said disk, substantially as set forth.
